If you're in a large league, an AL or NL-only league, a league with deep rosters or a league that tracks holds, you'll need to get a middle reliever. And you'll want a middleman who can do as many as possible of the following:

- Have a solid number of strikeouts per nine
- Get a lot of holds
- Have a strong chance of taking over the closer slot
Here are five middle relievers, all of whom are free agents in at least 80 percent of leagues, for your consideration.
